Sean Considine didn't know what a concussion felt like, but he learned the hard way.
The Ravens' safety was injured in the second preseason game vs. the Detroit Lions, and then he attempted to play the following week.
He didn't last against the Jacksonville Jaguars. Considine had to remove himself from the field.
"I didn't really get two concussions. I had one concussion in that second game and really I probably shouldn't have tried to play in that third game. That was all on me," Considine said, who hasn't worn the red, no-contact jersey for the last few practices including Saturday. "Just had some symptoms come up from the original."
He didn't play in the preseason finale in St. Louis.
The Ravens' secondary is its strength. Considine, who is in his first season here after leaving the Arizona Cardinals as a free agent, will play a backup role and on special teams. He's listed as probable on the Ravens' injury report for the opener Monday vs. the Cincinnati Bengals.
The head injury has made him wiser, and he's fortunate that his head injury wasn't more serious. The NFL has stepped up its enforcement and protocols for dealing with concussions and issues stiffer penalties, including fines for blows to the head.
"I just have a better idea what the symptoms of a concussion are. There not always easy to identify. ... Sometimes you feel like you're just sick," Considine said. "To be honest with you, that's what I thought I was going into that third preseason game."
"But once I got running around in the game I knew it wasn't just feeling bad or being sick. I knew I actually had a concussion," he said. "Going forward I learned a lesson of what the side effects of concussion actually feel like. I'm not sure I've ever had one before in my career so it was definitely a learning experience."
